Application filed October a, 1915, Serial No. 54,051.

To all whom it may concern:

Be it known that l, FRANK On'rrr, a citizen of the United States, residing at Indiana Harbor, county of Lake, and State of llndiana, have invented certain new and useful Improvements in Regenerator Constructions, of which the following is a specification.

This invention has reference to certain improvements in regenerator constructions.

The features of invention herein disclosed are particularly intended for use in regenerators for furnaces, such as open-hearth furnaces or the like, but said features can also be used to advantage in regenerators for many other classes of service.

In the ordinary type of regenerator construction, considerable difficulty is experienced in securing a uniform distribution of the gases over the entire body of the heat absorbing material, with the result that the material in some portions of the construction is worked at a higher degree of heat absorbing economy than in other portions; T he usual experience is that during the heating of the regenerator by the hot gases from the furnace, said gases will tend to remain in the upper portion of the regenerator chamber during their travel throughout the length of said chamber, and will only descend and pass out through the body of the heat absorbing material as they approach the back end of the chamber. his tendency is experienced because of the fact that the hot gasestend to maintain a higher elevation in the cham-. her than the relatively cooler gases. It is likewise found that on the other half of the cycle, the incoming cold air will tend to flow along the bottom portion of the chamber un-' til it reaches a point adjacent to the front end of the chamber, at which point it will rise through the checker work and then pass into the flue. This tendency is experienced by reason of the fact that the cold gases will remain at a relatively low position as long as possible. It is thus seen that during the heating portion of the cycle, the back end of the mass of heat absorbing material will be heated more than the front end of said mass and that on the cooling portion of the cycle, the greatest portion of the air will pass through the. front portion of the heat absorbing mass. It thus appears that not only is the heating efl'ect uneven in the difl'erent portions of the mass, but furthermore the Specification of Letters Patent.

air does not tend to pass through the hottest portion of said unevenly heated mass.

Une of the objects of the present invention is to so construct the mass of heat absorbing material so that there will be a tendency to secure a more even distribution of the hot gas during the heating portion of the cycle, and to secure a more even passage of the air during the cooling portion of the cycle.

In this connection another object of the invention is to so construct the heat absorbing mass that a maximum amount of heat absorbing material may be placed within a chamber of given size.

In this connection still another object is to so arrange the construction that the absorbing material embodying the features of the present invention may be readily built into a shell or chamber of the usual or customaryform, thus making it possible to secure the benefits of the present invention without necessitating complete reconstruction of the old style of regenerator chamber.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combination of parts, hereinafter described and claimed.

Referring to the drawingsFigure 1 shows a vertical longitudinal section through the body of a regenerator construction, having applied thereto one embodiment of the features of my invention; Fig. 2 is a horizontal section taken on the line 2-2 of Fig.

1, looking in the direction of the arrows; Fig. 3 is a vertical cross-section taken on the line 33 of Fig. 2, looking in the direc-' tion of the arrows; Fig. 4: is a vertical longitudinal section through a modified construction of regenerator, also embodying the features of the present invention; andFig. 5 is a vertical cross-section taken on the line 5-5 of Fig. l, looking in the direction of the arrows.

ll will first describethe construction shown in Figs. 1, 2 and 3. In this case the chamber is designated in its entirety by numeral 6.

The flue leading to the furnace is desiglid Between the rider walls 11, are the passages 12, which lead into the discharge opening 8, which also communicate with the bottom of the mass of heat absorbing material. Ordinarily the features of the present invention are applied to the upper portion of the heat absorbing material. In the present case, said upper portion comprises a plurality of longitudinal separated walls 13 and a plurality of pavements or partitions built into and between said walls. In the arrangement now being considered, these partitions serve the double function of providing dust-catching pockets, and of also controlling the passage of the air and gases through the different portions of, the heat absorbing-material, so as to secure the uniform distribution previously referred to. In the particular arrangement illustrated, the partitions are of two classes, some of them being horizontal and some of them vertical. The horizontal partitions are designated by the numeral 14 and the vertical partitions by the numeral 15. The partitions 15 extend a desired distance above the partitions 14, so as to establish dustcatching pockets, and they extend down into the body of the heat absorbing material a. distance suflicient to give the desired uni-- form gas distribution. If desired, there may also be provided across the front end of each partition 14, a tongue or the like 16, so as to improve the form of the dust-catching pocket, and there may also be provided beneath the front end of each of the horizontal partitions a plurality of supporting tiles 17. The walls 13 will ordinarily be placed as close together as possible, to secure the desired regenerator capacity, while at the same time permitting a free passage of the gases between said walls. However, at points between the adjacent edges of consecutive partitions 14, I may leave out portions of selected ones of the Walls 13, so as to provide the vertical flues or the like 18, best shown in Fig. 2. In the particular ar: rangement illustrated, the flues 18 v are formed by'leaving out portions of alternate walls 13, but manifestly said flues may be either larger or smaller than the sizes as thus determined. Furthermore, as shown in Fig. 1, the enlarged .fiues 18 not only extend downward past the partitions 14, but also extend horizontally beneath the partitions 14 for a distance of substar tially equal to one-half the length of said partitions, thereby providing the horizontal passages 19. These horizontal passages will insure a more uniform and perfect delivery of the gases into the body of the heat absorbing material 9. 1f desired, the doors or ports 20 may be formed in the side walls of the chamber opposite to the partitions 14, so as to facilitate removal of dust from said partitions. It will be observed from examination of Fig. 1 that the partitions. 15 extend down substantially to the heat absorbing material 9. These partitions constitute in effect bafiles to effectively control the passage of the air and gas through the body of the material and thus assist in securing the aforementioned uniform distribution. By regulating the sizes of the flues 18 and 19 in the different portions of the structure, the certainty of uniform distribution can be still further advanced.

Considering now the arrangement shown in Figs. 4 and 5, in this case the upper portion of the heat absorbing material also comprises a series of parallel walls between which gases pass in finding their way into the body of the heat absorbing material, but in this case said walls extend across the chamber instead of lengthwise thereof. These are the walls 21 and 22. The walls 21 are for the most part carried by a plurality of riders 23, which in turn are supported by the body of heat absorbing material 9. Between the riders 23 are the flue openings 24, and as shown in Fig. 4, said fiue openings may be carried down as far as may be desired, into the body of heat absorbing material 9. Extending lengthwise in the upper portion of the structure, is a channel or the like 25, by means or which the gases are delivered to the spaces between the various cross walls 21 and 2:2. Said channel extends down to a point near the body of heat absorbing material 9, where there is located a pavement or trough 26.

This pavement is in turn carried by the lower portions of the walls 21, and also by additional or intermediate shallow cross walls 27, which are set in between the lower portions of the walls 21. In addition to the foregoing a central partition 28 may be run up into contact with the lower portion of the trough 26, so as to more perfectly divide the stream of gases to the two sides of said trough. The trough may also be provided with the side walls 29 and 30. Across the upper portions of the partitions 21 there may be supported the pavements 31 and 32, and the cross walls 22 may be carried by said pavements. These walls 22 may be built up much higher into the upper portion of the chamber than the ordinary heat absorbing material construction, so that in this way a substantial increase in regenerator capacity may be secured within a chamber of given size.

While I have herein shown and described only two constructions embodying the features of my invention, still it will be understood that I am in no wise limited to said constructions, but include within the scope of my invention other equivalent constructions, operating in equivalent manners to produce equivalent results.
